Configuration: Call between two RT phones is not recorded

From DocWiki

Call between two RT phones is not recorded

Problem Summary

When a call is established between two RT phones (89XX and 99XX family), the call is not recorded by Unified MCP.

Error Message

State of the recorded conversation is ERROR.

Possible Cause

When a call is established between two RT phones (89XX and 99XX family), G722 codec is negotiated for the call. If G722 is disabled using service parameters, however, the 2 RT phones negotiate iSAC codec by default (Low Loss). Cisco MediaSense does not support G722 or iSAC codecs. Consequently, the call is not recorded.
